Lady Bowen, New York, 6 Aug 1872

I'm seeking the accurate time in days that the ship "Lady Bowen" navigated from Hamburg to New York when it arrived America 6 Aug 1872. Anton and Josephine Rzepinski and their family were aboard ("New York Passenger Lists, 1820-1957" - Roll M237, 1820-1897 - Roll 363, Page 332). I found their entries (in text - cannot find them nor recognize them in the original document) in "Hamburg Passenger Lists, 1850-1934" - "Direkt Band 026 (1 Jan 1872-30 June 1872)" - Page 329. That's 15 June 1872. I question about "Lady Bowen" voyage across the Atlantic in 52 days.
